About Our Physicians
On April 1, 1990, Kenneth T. Sim, M.D., F.A.C.S. started his medical practice in Southern California.
30 years later, Dr. Kenneth Sim and his group of surgeons have become one of the leading surgical practices, with expertise covering all areas of general surgery.
Medical treatment has evolved over the years and will continue to improve. Therefore, it is in the patient's best interest to seek out the physicians who continue to specialize and even sub-specialize within their own specialty. Our surgical specialists are driven by their passion for successful outcomes, and have each honed their skills into different sub-specialized fields of general surgery. To make sure their patients get the most advanced and up to date care, each surgeon continuously updates themselves with education and training to gain mastery of techniques and the latest/highest standards in areas such as robotic surgery, head and neck cancer, breast surgery, hepatobiliary, gastric cancer, colorectal cancer, and abdominal wall reconstruction/hernia repair.
Another important feature of our group is our customer service
. We have a unique blend of cultural diversity
. We understand the needs of numerous ethic groups and speak in their native language. Our staff and surgeons are fluent in the following languages: English, Spanish, Chinese (Cantonese/Mandarin/Taiwanese), Vietnamese, French, and Swahili.
The result is personal, individualized, culturally sensitive, and high-quality medical care. This is what we strive for every day, and we pride ourselves in providing excellent customer service and quality medical care.
